The United Nations (UN) is a body that was set up after World War II, in 1945. It was set up to encourage cooperation between countries and to act as a body that would respond to global threats and maintain peace and order in the world. It is made up of representatives from 193 countries, and is headquartered in New York.
U.N Decisions are not laws. But their mandates or discussions encourage leaders to find solutions and take good decisions.
